Be it known that 1, Lew s citizen of'f the United statea'residingat Frankfort onthe-Main, in the Kingdom of Prussia, Germany, have invented certain" Improvements in Machines for Treating;

Shoes with Liquids, of which the following description, in connection with the accom panying drawings, is a specification," like reference characters 7 on the drawings indicating like parts in the several figures.

This invention relates to machines for treating boots or shoes with liqu ds and 1s herein disclosed as 'einbodiedin a machine for cleaning the uppers of shoes. The machines of this character commonly used n shoe factories usually comprise a rotaryi brush, pad or other tool (hereinafter for convenience referred toa's a brush) and j of the brush. It will be evident that the some ineans for supplying the brush with a" cleansing fluid, such for instance as water. In order to secure the best results, it 1s'es-- s sential that the brush be supplied with a certain quantity only of water, too little being insuilicient to clean the shoe properly or requiring anundue length of time to perform the cleaning operation, and too much being objectionable in that it spatters o from the brush over the adjacent partsof the machine. The machines of this character at present on the market, however, have, so far as I am aware, no provision by which the quantity, of cleansing iiuid can be regulated to suit the requirements of the Work.

lit is therefore an important object of this invention to devise a machine having means for controlling the delivery of cleansing fluid tothe brush. Preferably this control is effected through the presentation of the work to the brush. In the preferredc'onstruction the arrangement is such that while the delivery of fluid to the brushtakesplace only when the brush is operating on the work, provision also is made for determining automatically the maximum rate'of delivery of fluid to the brush and for enabling the workman to vary the rate of delivery through the actionof the work on the brush. The invention will be clearly understood from the following description of one embodiment thereof when read in connection with the which,-

upper cleaning machine constructed in ac COlfllllCQjVlijh this invention, certain parts of the machine being tiong and Fig. 2 is a cross-sectional View on theline 2-2, Fig. l.

The machine shown in the drawings com} prises a rotary brush 1 mounted on a shaft 2,

I k I cut away in order to r i show more clearly the details ofconstrud mechanismconsists of a tank 8, a roll at ro- 1 tatably mounted in said tank and a second 1 roll 5 mounted/to rotatein peripheral contact both withthe roll l brush 1. The drag of the bristles on the roll 5causes it'to rotate and to drive the roll and also with the 4. The latter roll thus delivers water to the r0115 WlllCli' in turn carries it to the bristles rate of delivery of water to the brush will depend upon the rate of rotation of the roll 5 and in order to control this rate of rotation the roll is provide'd with a centrifugal brake. Thisbrake consists of a hub fast on thespindle of the roll 5 and two weighted arms 6 and 7, each pivoted to the hub and having attached thereto springs 8 and 9 re spectively which tend to turn the arms in Wardly about their pivots. This mechaf nisin revolves inside a stationary casing 10,

havinga peripheral flange which, overlies the weighted arms 6 and 7. The flange may, if desired, be lined with leather or f other similarmaterial as indicated :at 11. l'Vhen the roll 5 is rotated rapidly the weights 6 and? are urged outwardly by centrifugal inertia, against the tension of the springs 8 and 9 until, when theroll attains a certain speed, the'weights come in contactwiththe lining 11 of the stationary casing 10 and the friction created in this manner exerts a retarding action on the roll, preventing any further increase in its speed and, consequently,limiting the rate of delivery of liquid to the brush.

The tank 3 together with the rolls is mountedfor adjustment towardv and from the periphery of the brush, the adjusting ineanscomprising a cap plate 12 on which -the tank sits and an adjusting screw 13 which supports, the cap plate and is threadguideway 14: formed in the wall of the machine frame at each side receives a"projec-' tion from the tank 3 and controls the path of the adjusting movement of the liquid sup plying mechanism. a tank also may be with a water gage of the usual provided construction to indicate at any time the level ofthe' water in the tank.

liquid supply- Positioned front: of the 1 ing mechanism and atthelowersideof the 10- ent rely across and is supported in a' holder 17 having a 1 cylin'dricalfshank' 18 mounted'ina vertical brush is a stripper plate 16 which extends the periphery of the brush slideway formed'in thewalls of a basin 19 which constitutes part of the machine frame.

The lower end of the holder 17 is supported; on an adjusting screw 20 by means of which 7 the position of the stripper plate can be. ad-

- justed. Any turning movement of the plying mechanism is adjusted so that the roll 5 will be engaged firmly by the bristles of the brush and the stripper plate 16 is F into the body of the brush. When the mav chineis running idly, that is, when the brush" stripper plate is prevented by a set screwj21 V threaded through the walls of the basin 19' and entering a vertical groove in theshank 18 of the holder. Thewater that is scraped off the brush by the stripper plate 16 flows into the basin 19, and'is conducted away by a pipe 22 opening into the bottom of this basin. The brush is partly inclosed by a hood. consisting of a lower stationary section 23 and an upper section 24; pivoted to the lower section at 25. Y

In operating the machine the liquid supset with its upper edge'projectmg slightly is not operating on the worln Stripper f skipping the stripper plate 16, but straightplate will bend the bristles of their normal positions. An appreciable length of timeis required for the bristles to straighten out again; and due to the rotation or. the brush the ends of the bristles will travelduring their straightening action in a line substantially like that indicated by the line A, Fig. 1. This path, of course, will vary with the speed of 'rotationand the length and resiliency of thebristles of" the brush. It will thus be evidentfrom an inspectionof Fig. 1 that when the machine is running idly the effect of the stripper plate is to deflect the bristles in such manner that they entirely skip the conveying roll 5. Consequently the'actionof the conveyer is interrupted at this time and the delivery Of liquid to the brush is stopped. When, how-' ever, the work is pressed against the brush it then deflects the bristles so that in .returning to their normal positions they follow a path substantially as indicated for eX- ample by the'line B, Fig. 1, thus entirely emng out again in time to contact with the roll '5 and drive it in the usual manner; This arrangement not only results in causbackwardly out" ing the delivery of water to the brush to take place only when the brush is operating upon the work but also enables the workman to vary the rate of) delivery of liquid while the. a

work is being treated; for while the maXi-' mum rate of rotation of the roll 5 and consequently, the maximum'rate of delivery of liquid to the brush is determined by the centrifugalbrake, still the rate ofrotation of the conveyer roll will be less ifthe brush *engages the roll' merely with the tips of its bristles than if i a greater portion of the bristlescontacts with the roll. The workman, therefore, can vary the driving engagement; between the brush and the roll by pressing the work againstthe roll so hard that the bristles will only straighten out in time to have'theirtips contactwith the roll or by holding the work against the brush with a lighter pressure, thus enabling the bristles toresume their normal positions more quickly and to engage the roll more firmly. This control of the rate of delivery ofwaterto the brush is thus effected by changing, temporarily, the shape of the brush.
